Question

When is the only time that an object has no gravitational potential energy

Answer 1

when it is not moving or on the ground

Answer 2

The gravitation potential energy of an object will be zero when it will be at ground.

Step-by-step explanation:

The energy of an object due to its position is known as gravitational potential energy. Mathematically, it can be written as:

P.E = mgh ………… (i)

Equation (i) shows that P.E depends upon weight and height of the object above the ground. If h = 0 then,

P.E = mg(0)

P.E = 0

Hence, when the object will be at ground, its potential energy will be zero.
